Why pay for access when you can pay for data?
Hiring scaffolding for terraced properties in Brynmawr or Nantyglo can be logistically difficult and expensive.
Our drone survey provides a faster, more practical alternative:
- ✅ Evidence for Insurance: Validation for storm damage claims with 4K photos.
- ✅ Industrial Audits: Efficient scanning of large commercial roofs on the estate.
- ✅ Trace and Access: Find the exact entry point of a leak in minutes.
The Highest Town in Wales Is Hard on Roofs
Well above 1,300 feet, Brynmawr gets weather that lower valley stock never sees.
Sustained Wind, Not Just Gusts
Brynmawr, Nantyglo and Beaufort sit on open high ground with nothing upwind to slow the air. Ridge tiles work loose, verges lift, and slates are drawn out of their laps by repeated uplift rather than one dramatic event. Because it happens gradually, nobody looks until a ceiling gets wet.
Freeze-Thaw at Altitude
At this height a roof crosses freezing point far more often than the same roof would in Newport. Water sitting in a hairline crack expands, opens it, and takes the slate or the mortar apart over a few winters. At high zoom that cracking shows up early — while it is still a pointing job rather than a rebuild.
Rassau Industrial Sheeting
The Rassau and Beaufort estates carry acres of profiled sheeting, long valley gutters and translucent rooflights, all degrading in an exposed upland atmosphere. Walking those roofs to inspect them is the dangerous part of the job. Flying them is not, and it produces a better record.
We Do Not Quote for the Repair
There is no roofing arm to CalonTerra, so a Brynmawr survey has no commercial destination beyond the report itself: fixed fee, every raw image, the 4K video and a written assessment you can hand to a roofer, a managing agent or an insurer with no conflict of interest attached.
Buying or Selling in NP23?
"The survey flagged a potential roof issue."
Banks often demand a "Specialist Roof Report" before releasing funds on terraced or converted properties. Standard surveys often can't see high, complex roofs properly.
The Solution: We provide the high-level evidence your lender requires to lift the retention.
Insurance Claims & Storm Damage
If you are claiming for "Storm Event" damage, your insurer will demand proof that the damage is new and not just "wear and tear."
- ✅ HD Evidence: 4K photos of fresh damage.
- ✅ Date-Stamped Data: Proof for your claim.
- ✅ Independent Validation: Unbiased reports.
Typical Defects We Expose
Damaged / Slipped Tiles

Brynmawr Drone Surveys: NP23 Questions
What Brynmawr, Nantyglo, Beaufort and Rassau customers ask.
Is it ever too windy to fly in Brynmawr?
Sometimes, and we would far rather say so than produce blurred evidence. We work within the aircraft's published wind limit and check the forecast for the tops rather than the valley floor. If we arrive and cannot fly safely, you pay nothing and we rebook at the original quote.
Can you see wind damage that a ground inspection misses?
That is the main reason to fly here. Uplift damage begins at the ridge, the verge and the exposed hip, all of which we photograph directly and none of which are visible from the ground. A slate that has crept two inches out of its lap looks entirely normal from the street.
Do you survey in winter?
Yes, and winter is often the most informative time on the Heads of the Valleys, because freeze-thaw damage and blocked gutters are actively showing. We do avoid lying snow, since it hides the very surface we are there to record.
Are you insured to fly over occupied terraces?
Yes. We carry £5m public liability cover for commercial aerial operations and hold the CAA A2 Certificate of Competency, which is the qualification directly concerned with operating close to people and property such as a Nantyglo terraced street.
How much of Blaenau Gwent do you cover from Pontypool?
Brynmawr, Nantyglo, Beaufort, Rassau, Blaina and Abertillery all sit inside our regular working area. The travel element is calculated from NP4 for your postcode and displayed in the quote form on this page.
